LIGHTING FIXTURE.

Myinvention relates to that class of lighting fixtures which are suspended from a ceiling. In devices `of this kind, with which I am familiar, two worlin'ien are required, one to hold the .fixture while the other is connecting the wires on the .fixture to the wires issuing from the outlet or unction box.

My invention has for its principal object the improvement oi' the canopy and suspension devices. A further object is to entirely eliminate the necessity for more than one worku'ian, the structure being such that he will have the use of both of his hands Awhile the conductors are being connected.

A further object is to provide means whereby the fixture will hang vertically, regardless ot' the inequality oit the point oit union Vbetween the outlet or junction box and the ceiling.

My means t'or accomplishing the foregoing objects may be readily understood by reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which- Fig. 1 is a side elevation of my improved canopy and suspension device;

Fig. 2 is a vertical section of the device as shown in Fig. 1;

Fig. 3 is a vertical section showing the' means of sustaining the fixture (not shown) while the conductors are being connected; and,

Fig. 4 is a bottom view of the canopy with the chain omitted.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the outlet or junction box 11, which is of standard construction, provided with a central stud 12 upon which is mounted a coupling 13. This coupling has depending from it a threaded rod 111. A canopy 15, of any desired configuration, is placed in the position illustrated. This canopy 15 has both ends open, but is provided with a strap 16 which is cast, or formed, therewith, and is provided with a central opening through which the threaded rod 14 passes. A nut 17 is mounted upon the said rod 14 and serves to draw the canopy 15 tightly against the ceiling.

The canopy 15 is provided with a cap or cover 18, which isheld in position by means of screws 19 and 20 which are mounted in the strap 16 adjacent the wall of the canopy 12, 1925. Serial No. 8,682.

leading from the light- 28 leading from the outletor junction box 11. At one side oit the strap'll, adjacent the central opening through which the rod 14 passes, I cast, or vform, an upwardly eX- tending member 29 which forms a hook which is adapted to receive a link 30 of the chain 22. f i f In mounting atixture of this skind, the operator First screws the coupling 13 on to the stud 12v in the outlet or junction boa 11. The canopy 15 is then slipped upiover the downwardly depending threaded rod 14, this rod passing through the opening in the strap 16. The canopy 15 is locked in position by means of thelocknutl.y yThe house wires 27 and 28, extending from the outlet or junction box 11, are then pulled down through the canopy 15, as clearly seen in Fig. 3. The chain 22, from which the lighting fixture (not shown) is dependin, g,` is then lifted, and the linlr 30 is hooked on to the hookv 29 on the strap 16. In this position it will be apparent-that the operator can release the fixture (not shown) and employ both hands :tor the purpose of connecting the house wires 27 and 28 to the fixture sie wires 25 and 26. After being connected and i taped in the usual manner, the wires can then be pushed up into the canopy 15, as clearly shown in Fig. 2.

The link 30 is then detached from the hook 29, and the cover or cap 18 on the end of the chain 22 is slid up and over the heads of screws 19 and 20., openings 31 and 32 being provided for thispurpose. The cover 18 is also provided with arcuate slots 33 and `311, leading from the openings 31 and 32. These slots are litted'to the body of the screw, so as to permit the rotating of the cover 18 until the body of screws 19 and 2O enter slots 33 and 34, which being narrower in width than. the diameter of the heads of screws 19 and 20, serve to secure the cover 18 'so that the workman vcan haveboth handsfree to tighten the screws 19 and 20, and` :thus complete the installing of the fixture. i

AIt will be apparent from the foregoing description that Ilfliave overcome the necessity for a. second Workman to hold the 'fixture while the house wires are being yconnected to the fixture wires, and also that this construction insuresthe fixture being suspended vertically. y i y Although I have' shown and descril'ied a specific :form of -construction, it `will be understood 'by persons skilled in the art, that numerous changes may be made, and I do not. ydesire to lbe runderstood as limiting myself to the specific details thus illustrated 'and described.

-Having thus described my invention, what I regard as new and desire to secure by United States `Letters Patent is: y i

1. The combiniiltion with a lighting fixture of .an outlet box, a threaded rod which depends therefrom, a canopy having both ends 'opeina strap which extends across the lower opening, 'there bei-ng a central openingin said` strap -thi'ough which said rod passes, 'a nut onsairl rod which holds said canopy against the ceiling, a cover for the lower end of said canopy, said cover having an 'eye therein, a chain linkedn 'in said' eye, a hook on said canopy adapted tohold said chain while the fixture is heing'wir'ed, said holding means being independent of the securing means for the fixture, and means to securesaideover tosad canopy.

'2; rThe combination with a lighting iixture of a junction box, a canopy secured thereto, a cap for said canopy, means to secure a chain to said cap, means to secure said cap to said canopy, and means integral with said canopy to engage one of the links of a chain, said means being independent of the securing "means for the fixture.

3. The combination with a lightingIr fixture fof :a `junction box, a, coupling secured thereto,

a rod which depends therefrom, a canopy lmounted on said rod, means to 4hold sald canopy `in position, a cover for said canopy having an `.eye formed therein, a chain mounted in said eye, a hook on said canopy adapted to hold said chain while the fixture is being wired, said holding ineans being independent of the securingr means for the fixture, and means to secure said cover to said canopy.

el. The combination with a lighting fixture l tion, a chain linked into an eye formed on said cover, a hook adapted to hold a link Vof said chain', said means being independent of the securing means for the fixture.
